基于PSoC的触摸感应控制器设计与实现

The Design and Development of Touch Sensing Controller Based on PSoC

针对机械式控制器设计与应用的局限性,采用PSoC(片上系统)作为处理器,开发了一种新型的触摸感应控制器。该系统应用CSD原理,以及独特的设计方法改善了触摸感应控制器设计的灵活性和开发周期,利用I2C—USB Bridge实时调试提高了感应控制器设计的可靠性。调试结果表明,该控制器运行稳定可靠,具有一定的实用性和推广价值。

A new type of Touch Sensing Controller with modern SoC （System on Chip） processor and control technology is developed.The flexible and efficiency of design method has been improved due to the special design of controller. The CSD （Capacitive Sensing using a Sigma-Delta ） theory and real-time debugging technique has been used to improve the reliability of controller design. The application shows that this system runs stably and accurately. The technology and methods adopt in the system are practical and worthy of using abroad.
